4: these two lines are extremely important because they will ignore the errors during installation of Pillow, without these two lines the setup cannot be finished (I am using python 2.7 so you may need to change whatever version you use):

Did you check after the compile all the tests in Tests directory of Pillow are passed?

No I haven't checked the Tests directory. But Before installation I got errors. After the installation I ran this command python -c "from PIL import Image" No error was shown.
